Ok let me clear up a few thing here cause i have also done extensive research on these things.

First the A32 and 33 VQ's ARE different. But the main difference is that the A33 models(2001 +) come with variable Dual intake runners(black upper intake manifold) as opposed to the Single intake runner(silver upper intake manifold). It's called the VIAS system. Look it up.

In the VQ3.0 an up it gives as much as 30hp up top as it only activates at 5000RPM. With regards to the manual for the A33, i don't think they ever came in manual, as in the states they are known as the infiniti I35 and never came with a gearbox. I have done extensive research on it an yet to come across a manual version. The A32 u can get a manual conversion for it.

cacasplat3 i to have a A33 and realise the only options is to go bigger displacement as u will run into problems with engine management. So far yur options are JWT(u will need to get an older ecu and they will have to mod it to work) Technosquare (they upgrade 2001 an up but no-one has proven there theory of increased rev limit) and then there is the proven Greddy e-manage ultimate( u get to increase rev limit, remove speed limiter, adjust timing, a/f ratio an a whole lot of sheit.).

u can boost the engine u have but is real stress an i also have not seen anybody who boosted over 10psi. An i don't think u can get aftermarketparts like pistons an rods, i could be wrong.

With regards to brakes, the 300zx setup is a direct bolt on. u jus have to mill the diamater bout 2-3 millimeters for it to clr the calipers. an u will need to increase the size of yur rims to at least 17's.

Suspension wise, tokico makes a complete shocks and spring setup that lowers the car 1.5 inches in front and 1.3 in the back. also it is 5 way adjustable for only $600US. which is cheaper that the stock setup from N&M.

The A33 is a very heavy car which is y de primera's can do it to us.

U can put in the VQ35 which is the grand master but it's alot of work and literally to much headache as the electronics are different,(uses drive by wire throttle), also u will need to find a way around the stock anti-theft system which is a pain!!!

cdx2k1 - the rods and valve train and head bolts need to be upgraded only if u plannin to hit more that 7200RPM. Only then will it break it. Also the VQ35 rods not a beefy as the VQ30 so most of the times guys use the VQ30 to modify.

I have links to back up all my stuff so pm me if u want to find out more.

Rodney T, good info, i'll save this thread,
as for the vq3.5 it have ah fwd version? Confused

i though the closest one was the 3.4 which came in the newest cefiro.
i still preffer the tein coilovers, cuz of the fact that it ajustable, like if u know u wah carry it to dex for ah lil run, u just drop it ah lil extra, i never liked the fixed droping systems, cuz if u were to strip yuh car of the interior u could end up with ah uneven looking ride height.
was wondering if there is any electronic system that you can use that will completely elliminate the need for the original ecu, (i mean like a new aftermarket device which can run the entire system) that would make life easier.
but the more and more i think about this, the less and less i want to do it. i think i'll stick to just staying n/a but with a lot of tuning, cuz the boost part sounding real costly. Crying or Very sad

Yes it have a FWD version, but it is to much work to convert IMO. i can send u a link detailing what is necessary to convert to the 3.5L. an u cannot use a 350Z 3.5L. and a FWD transmission would not work.

The tokico shocks i mentioned is adjustable- 5 ways with a screwdriver.
only the springs is fixed. the shocks adjustable.

with regards to stand alone engine management i not sure. seems that the car has a lot of electronics that may not work with a stand alone. remenber our car's transmission is electronically controlled, an i don't mean like dem b14 or almera. we have a separate TCM(transmission control module) to deal with that. Our car uses solenoid valves to change gears. So u would run into problems.

i know the 350z vq was out ah the question, i remember watching an episode of monster garage where they swapped a vq35de into a 2-door 120y for drifting. the electrician who had all the wiring diagrams, and a lot of experience with top of the line engines took about 2 days to figure out the wiring system, that was pressure for him, so doh talk bout the electricians we have here.
today i do some thinking, 6psi of boost, with all relevant electronics, and suspension/brakes upgrades. should be less work than @10psi, do you think the internals cand hold up to the 6 psi?
another thing

the american altima SER had a gearbox that can work on the vq20 ... and most of the 350Z mods will mork on this engine

x2floor · Posted: Thu Jul 27, 2006 2:51 am Post subject:

here is my 2cents:

you have an a33 cefiro and obviously want more power. ofcourse $$$ is needed so what is your budget? how much cash willing to dish out? i assume that you wanna keep your car for quite a long while and have reliable operation even after a swap plus the added benefit of having warranties for the parts correct?

then, maybe rodney could clarify but drop a VQ35DE in and replace the tranny with a Nissan 350Z/Nissan Maxima (USDM)/Nissan Altima SER/Infiniti G35 6-speed manual or get the more powerful 5-speed automatic/manumatic tranny lifted from an Infiniti I35/Infiniti M35/Infiniti G35/Nissan 350Z etc etc

get your parts from JWT like:
S1 Billet cams, valve spring & shim kit, friction plate kit, clutch set, sports flywheel, pop charger, gt40r turbo, ceramic headers

thats 39HP added to stock 300HP if you get your VQ35DE from the 350Z and 6-speed manual tranny. So you have 339HP not including the boost you will get from that turbo. Im sure you will clock 500HP+

you can also add the stillen valve body upgrade for the automatic tranny if you choose.

other stillen parts that u can get are:
hks super fire plugs, stillen performance alluminium radiator (if you choose the 6-speed tranny)

another upgrade is the borla cat-back stainless steel t-304 exhaust with a turbo muffler 2.5" diameter.

and lastly a Brembo sport disc OEM replacement rotors (ventillated and cross drilled) with Ceramicool pads to work on the stock calipers should do fine.

Mr. Green

You can have the baddest Cefiro in T'dad with a very bad price!

ofcourse, there is the added benefits of a coilover suspension, high performance toyo proxes tyres, 17" or 18" light weight rims, forged light weight pistons and NOS with some definite access to C-16 Shocked

imagine a cefiro runnnin 11s on the 1320!! Shocked

hmmmmmmmmmmmm well look thing, ah man say $30,000. that eh bad to do 11 seconds. but i eh wah swap out the engine, i wah keep the original engine and just drop some mod's on it. just got an e-mail back from tein, they said they cant guarantee fitment of any of their parts on the cefiro, althought there is a guy in malasyia who has a set of tein's on his cefiro (no modifications to anything)
rodney, the brembo rotors, how much for them?(and where can i get them) i think right now i have a bent front rotor, cuz when i holding brakes over 90kmph the steering vibrates a lot. Shocked

i really want ah gearbox, but if i cyah get one to fit, small thing. tranny for that. Mr. Green

i eh wah NOS, i just want ah daily driver that could eat the black off the road.

^^^^^^^3 useful websites for you:

www.jimwolftechnology.com
www.stillen.com
www.autoanything.com

the last website has exactly what you looking for, OEM brembo replacement rotors and ceramicool pads. All what i mentioned came from those 3 sites.

as for you keeping your VQ20DE, sry pal, your options are quite limited. I suggest doing minor stuff like machining your cams to create slightly higher lift and duration; a CAI and an upgraded exhaust 1.5 to 2" perhaps. More experienced people should tell you cause you dont wanna lose torque.

It doesn't make sense really spending all that money on a vehicle that would still strain to out accelerate a stock SiR or even try to ketch a ITR. I say, u want daily driver with hott performance but staying with a Nissan formula then get a p11 primera already with a SR20DE and work your magic there. The possibilities are endless. Hell even a B13 and B14 can be acquired just for racing fun. S14s and S15s too. Let the Cefiro pamper you will its soft suspension and Toyota Crown like ride and prevent it from being embarassed by a car costing half the price. Smoke-em with a smaller SR20DET vehicle. Mr. Green

thanks for the links, i'll read them. you have a point about getting smoked with the 2.0 but with a 3.0 and boost, hardly likely i'll get smoked from the ususal highway runners. Mr. Green

a proper 3.0 would be one from the infiniti i30 or if i could find one sumwhere at all.
but according to this:

^^^interesting, i got my specs from one of nissan's websites. the figures are for jdm but wikipedia was known to give slightly off information. nevertheless, i really hope its correct though. take into consideration the specs i posted are DIN not EEC or SAE. thanks 4 the info Smile

cacasplat3 · Posted: Wed Aug 02, 2006 8:09 pm Post subject:

have to dyno the car, but not right now, cuz i doh have the time.
i really considering the swap out instead of modding the original, or a larger engine.
most likely ah sr20det will be the engine used, its lightweight, and produces quite a lot of power when compared to a modded vq20de, the sr also has a bigger market for aftermarket parts, which will make modding a lot easier. Wink

^^ i am no longer swapping out jed..

i wanna get ah new ride for de project later on.. this FWD givin me tro much or ah bottleneck interms of engine choice.. i really wanna go 2jz or rb25det or rb26dett
